DESCRIPTION (Figs. 1 and 2)
The valves are equipped with different types of operators
depending on the version used.
A Positioner
D
positioning unit made of PA (polyamide) 6/6
GF 30% (glass fibre reinforced) equipped with a metal ca-
ble gland for cable dia. 4,5 - 9 mm is standard fitted on the
valves. It includes a linear potentiometer, a processor and
two pilot valves.
- Single loop control
- Double loop control for positioner with directly connected
external sensor.
APC software for modification of control parameters is available
for download at: www.asconumatics.eu. The APC software is
required for double loop control.
The Positioner
D
with double-loop control is delivered ex works
with factory settings (positioner). The device must be mounted
on the aseptic valve and initialised with these factory settings.
The APC software can be used to set the Positioner
D
to double-
loop control in the Custom Parameters only after initialisation.
Initialisation may only be performed with the factory settings.
The proportional valve is factory-adjusted. The Positioner
D
is equipped with an electronic “shut off” system to exhaust
the pilot chamber at 0 setpoint to ensure that the valves are
tight when closed.

OPERATION (Figs. 1 and 2)
NC – Normally closed: The valve is closed when no pilot pres-
sure is supplied by the positioner to the actuator.
The valve opens when the positioner supplies a pilot pressure.
In the auto-adjust phase, adapt the pilot pressures according
to the actuator:
2 to 3 for an actuator with very low pilot pressure (1,5 b)
3 to 5 bar for an actuator with low pilot pressure (2,5 b)
5 to 7 bar for an actuator with high pilot pressure (4 b)
On loss of power the valve returns to the fail close position
or the disc position is maintained.
INSTALLATION AND PUTTING INTO SERVICE (Fig. 3)
The device is supplied factory installed and adjusted.
The final installation consists of connecting the electrical and
pneumatic supply; the device is then ready for operation in
accordance with the setpoint values.
The green LED 3 lights up when power is ON.
The bottom LED 4 (orange) lights up when the valve is fully closed.
The top LED 1 (yellow) lights up when the valve is fully open.
A rapidly flashing red LED 2 indicates a device malfunction,
see “Error Definitions” on last page.

ELECTRICAL CONNECTION (Fig. 4)
All electrical connections must be made by trained and
qualified personnel only and be in accordance with your local
regulations and standards.
In order to ensure EMC protection, the device must be con-
nected to earth with a shielded cable. On the device side,
the shield must be connected via the metal cable gland and/
or via a shielded connector (M12). On the control side, the
cable shield must have a low-impedance connection to earth.
1) Connection by cable and cable gland
CAUTION:
• Beforestartinganywork,turnofftheelectricalcurrent
and shut off the air supply to power off the components.
Unscrew and remove the cover.

All screw terminals must be properly tightened prior to op-
eration (be sure to observe a tightening torque of 3 Nm).
The electrical connection is made by a metal cable gland
M16 x 1,5 mm for cable dia. 4,5-9 mm (tightening torque: 3 Nm).
Put the cover and its seal back in place (be sure to observe
a tightening torque of 5 Nm).

2 – To switch to manual mode, simultaneously press the “Open”
button (no. 3) and the “Close” button (no. 4) until the green
LED flashes.
3 – Press the top button to open: The valve will open as
long as the button is pressed, it will stop opening as
soon as the button is released (fig. 7).
